Another vote for Valentine1. I've had mine for over 10 years and it has more than paid for itself. They support their product and stand behind it; I sent mine in a few years ago to have the software updated but otherwise I've done nothing to it and it's been flawless.

The other brands have finally caught up in performance but the arrows are patented; you will find these incredibly useful and only on Valentines. Further, when Mike Valentine left Escort back in the 1980's, he did so because the industry was producing CRAP detectors. He struck out on his own, and IMO, single handedly raised the bar for performance and quality.

Valentine is a small American company based in Cincinati and unlike some, they truly deserve your business.
